World of Warcraft 64-bit client soon?

According to the latest changes in the interface files of the Patch 4.2 PTR client, it seems that Blizzard is finally getting ready to release a 64-bit version of the WoW client.

Well, this change means two things:

• People with 64-bit Operating Systems (= anyone with more than 3gb of Memory, most likely) will see a slight increase in performance.
• People who regularly experiences crashes when World of Warcraft uses too much memory will finally be able to play WoW without crashing every x hours/minutes. (People playing in super high resolution, or with a boatload of addons)

Of course nothing is official yet, but there's a glimmer of hope for the increasing number of people with 64-bit systems. However, I'd like to point out that we're only seeing a couple of strings in .lua files and not real changes so I wouldn't expect it for Patch 4.2.
